On Tuesday, Floyd “Money” Mayweather and Saul “Canelo” Alvarez kicked off the Vegas fight week festivities when they arrived at the MGM Grand in Las Vegas. The atmosphere was electric well before the fighters finally arrived. The raucous crowd was primarily in favor of Alvarez, the 23 year-old Mexican but that only seemed to excite Mayweather. Despite reigning as the world junior middleweight champion, Alvarez has never been in a fight this big (how many boxers have?). But if the magnitude of the event has started to get to Alvarez, you would never know it. He greeted fans with his customary smile and appeared confident, just as he has throughout the build-up to this huge event.

On Wednesday, the main event fighters were brought together at a press conference inside the KA Theater at the MGM Grand. One notable absentee was the nominal promoter of the event, Golden Boy CEO Oscar De La Hoya who will not attend the fight because he checked himself into a rehab facility. “Oscar reached out to me the other day and told me that he had experienced a set back and would be admitting himself,” said Golden Boy's Richard Schaefer on Tuesday. “It is bad timing but when you’re sick you can’t just wait until next week.”

Neither Mayweather nor Alvarez had much to say at the press conference but, unsurprsingly, Mayweather was a bit more outspoken. “I’ve been here so many times and I’m just fighting another guy. Canelo is fighting Floyd Mayweather, the best in the world,” said Mayweather. “Canelo Alvarez is 42-0 but he hasn’t fought 42 Floyd Mayweathers. If he had he would be 0-42.”

Floyd Mayweather Sr., who trains his son, told Boxingtalk Alvarez is in over his head. “Floyd is going to be too fast for this guy,” claimed Floyd Sr. “I’m telling you that Floyd is going to hurt him to the body, maybe two or three times.”

Zab Judah,a former Mayweather opponent, also weighed in on what he thinks will happen. “I think Floyd is going to outbox him. I have been in camp with Floyd and have seen how sharp he is. I don’t think Canelo can catch him.”

If Tuesday was any indication, there will be fireworks in store at Thursday's undercard press conference. Danny Garcia and Lucas Matthysse will battle for Garcia's world 140-pound championship. Garcia’s father/trainer Angel will likely to steal the show with outrageous comments.
